Chemical Structure

Tadalafil Impurity 52 CAS 5345-73-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 141.98 g/mol gives Tadalafil Impurity 52 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Tadalafil Impurity 52 (CAS 5345-73-3) is a certified pharmaceutical impurity reference standard with the molecular formula C3H5Cl2NO and a molecular weight of 141.98 g/mol.

Based on its molecular formula C3H5Cl2NO, Tadalafil Impurity 52 contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 141.98 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO manufactures Tadalafil Impurity 52 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
